DEVICE FOR LUBRICATING SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 564,366, dated July 21, 1896.

Application filed January 10, 1895. Serial No. 534,445. (No model.)

T0 all whom, it may concern:

Be it known that we, JOHN DAWSON and ROBERT SoUTHwoETH DAwsoN, subjects of the Queen of England, residing at Bradford, England, have invented certain Improvements in Devices for Lubricating Spinning- Spindles, of which the following is a specification.

This invention relates to improvements in the tubes and whirls of spinning, doubling, and twisting machinery and in the means of lubricating the same. y

Reference is to be had to the accompanying sheet of drawings, formingapart of this speciiication, in whichy Figure l represents an elevation of our improved tube, whirl, and lubricating device mounted on a portion of a spindle. Fig. 2

` represents a vertical section of the same with the central portion of the spindle broken away. Fig. 3 represents a plan of Fig. 1. Fig. 4C is a separate View of the lower end of the tube. Fig. 5 represents a separate diametrical section of the whirl, and Figs. 6 to lO are views of details hereinafter referred to.

The tube A may be either loosely attached to the whirl B, as shown in Figs. l, 2, and 3, or it may be rigidly fixed to it, as shown in Fig. l0. In the former case a lip or collar A2 is formed around the lower end of the tube,

and this collar is passed into a recess B2 and is retained therein by the wire ring B3, Fig. 9, sprung into the annular groove B4, formed in this recess. This arrangement leaves the whirl in a great measure free to revolve without the tube. To carry the lubricant from the whirl B and spindle O up the tube, we cut a shallow helical groove or female screwthread a from the bottom of the tube-that is to say, from the top of the whirl-approximately to the top of the tube, with the eX- tremity of the spiral at the lower end pointin gtoward the direction of rotation. Ve find with the helical groove arranged in this way that the tube is perfectly lubricated without any tendency to flood the spindle and waste the lubricant, as is the case when the helical groove is carried right down to the bottom of the whirl. For this reason in case the tube is rigidly xed to the whirl, as in Fig. 10, we prefer to leave a plain or ungrooved portion at the lower end of the whirl B. A convenient way of doing this is to only pass the tube A3 a certain distance through the whirl and introduce a short plain piece of tube A4 into the lower end of the whirl, leaving more or less of an annular, space between the upper end of A4 and the lower end of A3.

The lubricating device consists of a cup D, resting upon the lifter-plate E, concentric with the spindle O. The center of this cup is turned or raised up around the spindle so as to form an annular reservoir D2, in which the usual felt wad or wads F are inserted. The wad or wads are covered by the perforated plate G, resting upon the shoulder D3, formed around the cup. The plate G carries a washer H, preferably of conical form, upon which the projection B5 at the bottom of the whirl4 revolves. A cap J, having a dished top J 2, through which a central hole J 3 is made for the spindle, is fitted inside the top of the cup. The projection B5 is made slightly conical or bell-shaped, so that it is larger in diameter at the bottom than immediately above, and this larger part is placed well below the top of the cap J. Consequently centrifugal force prevents any tendency for the lubricant to iiow up outside the projection B5, and any which may be thrown olf at the bottom is collected by the cap J and falls back into the cup below.

Fig. 6 represents a separate diametrical section of the cap J. Fig. 7 represents a similar View of the cup D, plate G; and Fig. 8 represents a plan view of the same and the wad F also.

The cup is supplied with lubricant by pouring it into the dished cap, and it falls through the central opening onto the conical washer l-l and is distributed to the wad.

Instead of cutting the wad with a central hole approximately fitting the spindle we may cut it with a heart-shaped hole P, asshown in Fig. 8, or other suitably-shaped hole, adapted to only expose a comparatively small surface in direct contact with the spindle, as we find with the large reserve of lubricant the cup D is capable of retaining that it is quite possible to lubricate the spindle too freely if the wad is in contact with the spindle all round.

WVe claiml. The combination with a spindle of a spin- IOO ning or twisting machine, of a Whirl, a tube connected with the whirl, a non-rotary sheet Inet-al lubricating-cup having a rentrant bottom with a central perforation for the passage of the spindle, the said cup being located below the whirl of which it is independent, an absorbent packing for the cup, and a cap for the cup having a central perforation for the passage of the end of the whirl, said perforation being larger in diameter than the diameter of the end of the whirl that passes through it, substantially as specified.

The combination with a spindle of a spinning or twisting machine, of a whirl, a tube connected with the whirl, a lubricating-cup having a rentrant bottom with a perforation for the passage of the spindle, a felt washer located in the cup and having a central opening of irregular outline so that it does not tightly iit the spindle, a perforated plate su pported by the cup above the felt washer, a washer having a central perforation of larger diameter than the diameter of the spindle so that it does not make contact therewith loosely7 placed between the top of the plate and the bottom of the whirl, and a cap for the cup with a perforation to receive-the end of the whirl, substantially as speciiied.

3. The combination with the spindle of a spinning or twisting machine, of a whirl, a

tube connected with the whirl, a lubricatingcup formed of sheet metal with a rentrant bottom with a central perforation, a iibrous pad located within the cup and having a central spindle perforation, a perforated plate located within the cup above the pad, and a cap having a rentrant top with a central perforation for the passage of the lower end of the whirl, the said walls of the cap fitting into the side walls of the cup and resting upon the top of the perforated plate, substantially as specified.

4, The combination with the spindle of a spinning or twisting machine, of a whirl having a portion of its lower part smaller in diameter than its lower end, a lubricating-cup below the lower end of the whirl and a vcap with a rentrant top and with its edges loosely iitting into the upper end of the lubricatingcup with a central perforation that encircles the lower part of the whirl above the enlarged end, substantially as specified.

In testimony whereof we have hereunto set our hands in the presence of the two subscribin g witnesses.
